12.3 Amplifier Registers Used in Operational Amplifier
(1) Peripheral enable register 0 (PER0)
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
The operational amplifiers use the following four registers.
• Peripheral enable register 0 (PER0)
• Operational amplifier control register (OAC)
• A/D port configuration register (ADPC)
• Port mode registers 2, 15 (PM2, PM15)
PER0 is used to enable or disable use of each peripheral hardware macro. Clock supply to a hardware macro that is
not used is stopped in order to reduce the power consumption and noise.
When the operational amplifier is used, be sure to set bit 5 (ADCEN) of this register to 1.
PER0 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
